官网强调的特性：

Multithread Optimized
The Lockless memory allocator uses lock-free techniques to minimize latency and memory contention. This provides optimal scalability as the number of threads in your application increases. Per-thread data is used to reduce bus communication overhead. This results in thread-local allocations and frees not requiring any synchronization overhead in most cases.
